A test of 24 hours should be enough to ascertain if the voltage loss is the same or less than it was previously. Before I made this change the circuit was losing about 0.27 volts per day which would give the battery a life of about a week with 2 second reads/transmits. Ultimately the sensor will be set to only wake up every 60 seconds, which will give a much greater battery life.
